[PATCH 0/3] gpio: fix SRCU bugs

Posted by Bartosz Golaszewski 1 year, 10 months ago

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Here are three fixes to some bugs in recent SRCU changes. The first one fixes
an actual race condition. The other two just make lockdep happy.

Bartosz Golaszewski (3):
  gpio: take the SRCU read lock in gpiod_hog()
  gpio: cdev: use correct pointer accessors with SRCU
  gpio: use rcu_dereference_protected() to make lockdep happy
